Figure 8 is a further modification. Figure 9 isa top plan of adetailof Figure. .The invention primarily Yconsists of Va baseplate I having a pair of upstanding apertured lugs 2 arranged to straddle the Vbase of a rail 3. This `base-plate is preferably made from a rolled section of metal so that when in its nal formV the line l the fibrous structure of the metal is at right an-V gles to rail-holding stresses. In practice this means that the fibrous structure will be atright angles to the rail. The surface of the base-plate`v l between the upstanding lugs deviates from the vthe rail 3 and the top of the plate l. Wedgesl 5 are then driven through the apertures'in the lugs 2 so as to flex the clips 4 downwardly, the latter then resiliently holding the rail 3 down.

' The plateI is, of course, spiked to a rail.

' The wedges 5 are each formed with a pairo projections 6, one of which is higher than the other. When inserted in` the apertures of the lugs 6 one of these projections will drop in the apertures in the clips 4, Ylocking the wedge in place, and the opposite wedge will press against the top of the aperture in the lug, and by insertinto the aperture of oneoffthe lugsY without'the nrotate fthe. ,'pinV -esothatoneorl the -otherzof its #cylindrical .sides-dsforcediinto the apertures'in the eclips, fthe other 1, side fpushing fagains't lthe top Yofthe ilugfand fapplyingtension toi'the .rail

One 'example consists .of a cam-shaped member I0 having a' wrench operable end II andv a stub-shaftl.LV A'second Vmember exactly similar tothis, with the excep tion of the stub-shaft, is bored so that it can Ybe is used by slipping the stub-shaft I2l through' the aperture in the lug 2 and placing the bored member over it, the ring portions I3 ofv each vhaving a flattened part which permits this Operation without depressionofthe clips 4. A wrench may then be 'applied to the two members .to rotate them so that the ring portion drops into the aperture kin the top clips and the cam surfaces I0 depress the same. Further rotation will then vary thev tension applied to the base of the rail. The degrees of variation possible areonly limited by the number ofthe camvsurfaces I0; x

, The spring clips 4 have been shown tted' over the lugs `2 in vpairs in each instance. ,This is preferable because of the greater degree of flexribility provided. However, a single heavier spring Vclip might be used. 1f it is desired to hold the rail solidly, rigid steel clips I4Y may be used, their parts which contact thev pins being slightly upwardly bowed to springingly hold the retaining pins in place. f Y

Y Although specific forms of this invention have been shown and described in accordance with the patent'statutes, it is not intended to limittheir scopev exactly thereto, except as defined by the following claims..

We claim:

V1. A1 railway tie-plate assembly including a base-plate having an upstanding apertured lug,

structed to contact said base-plate and thebase of said rail, and means having a plurality'of difdifferent positions to hold down said clip with relatively different forces.

2. A railway tie-plate assembly including a base-plate having upstanding apertured lugs arranged to straddle the base of a rail, spring steel clips apertured for plural fitting application over said lugs and constructed so that in each instance the lowermost clip bridges between the base of said rail and said .base-plate and means that can be inserted through said apertured lugs to ex said clips downwardly. l

' 3. A railway tie-plate assembly including al base-plate having upstanding apertured lugs ar' ranged to straddle the base of a rail, spring steel clips apertured for plural fitting application over'A said lugs and constructed so'tha'tin each instance the lowermost clip bridges between the base ci?y said rail and said basepl'ate and adjustable .tact said base-plate and thebase". of;,said rail, and

Wedges having 'diierently sized. opposed projections on their sidesandconstructed for insertion through said apertured lugs with .one or,another of these projections extending down in the apertures in said, clips.

5. Arailway ltie-plate assembly including a A 1,998,043 A I l base-plate having upstanding apertured lugs arranged to straddle the base of a rail, clips apertured to t over said lugs and constructed to contact said base-plateand the base of said rail, and pins having flat sided ends with central eccentric cylindrically sided bodies which are fiat- Vtened at points permitting free insertion in said apertured lugs.

, 6.` A railway tie-plate assembly `including a base-plate having upstanding apertured lugs arranged to straddle the base of a rail, clips apertured to t over said lugs and constructed to contact said base-plate and the base of said rail, and cam faced concentrically ringed members having Wrench operable endsv and stub-shafts andl other cam surfaced concentrically ringed members constructed to fit said stub-shafts when insertedthrcugh said apertured lugs, each of these members ringed parts having a flattened portion permitting its free passage over the apertures in ksaid clips, p v

.'7. A railway Vtie-plate assembly including a base-plate'having at leastl one upstanding apertured lug arranged adjacent the base of a rail, at least one clip apertured to t over said lug and constructed to contact said base-plate and the basegofsaid rail, at least one cam-faced member vand, means insertable through said lug for holding said member with the cam surfaces there- `vof pressing against said clip or clips. g; g
